Where is Scorpio in the starry sky!

At eight or nine o'clock in the evening in summer, there is a bright star in the south that is not very high from the horizon. It is the alpha star of Scorpio. Because there are many dark stars in the low sky in the south at this time, which is very obvious. After finding this star, it is not difficult to recognize the rest of Scorpio.

Scorpio is the most conspicuous constellation in summer. There are many bright stars in it, and there are more than 20 brighter than 4m. Scorpio is big and bright, with many stars, which can be said to be the representative of the summer night constellation. In addition, it is also a zodiac, so it is particularly eye-catching. However, Scorpio only occupies a short range of 7 on the ecliptic, which is the shortest ecliptic among the twelve constellations.

This is the star map of Scorpio (attached figure:/pic/119548248451224.jpg). You see, it has two big pincers, and its poisonous tail is cocked high, and it flies arrogantly across the southern sky, so that several constellations next to it are too scared to speak.

Scorpio is immersed in the vast galaxy from alpha star to long scorpion tail. Alpha is located in the scorpion's chest, so the west calls it "the heart of Scorpio". Interestingly, in ancient China, the alpha star of Scorpio was placed in the center of 28 nights, which was called "Antares". You see, astronomers in the East and the West happen to coincide.

M7 open cluster M7 is one of the most famous open clusters in the sky. This cluster has many bright blue stars. At night, we can see it from the tail of Scorpio with the naked eye. M7 is about 1000 light years away from us, and consists of about1000 stars, with an age of about 200 million years and a size of about 25 light years. The above color photo was recently taken by the Kitt Peak National Observatory in Arizona, USA, and it is part of the Advanced Observer Program. As early as ancient times, people began to know about the M7 open cluster, which Ptolemy observed in 130. You can also see the dark dust clouds at the bottom of the constellation frame and millions of stars in the center of the Milky Way that have nothing to do with clusters.
